Four-syllable transliteration of 'Jedidiah' (Jed-i-di-ah → Jié-dí-dài-yà). It's a Hebrew Old Testament name — a second name given to King Solomon in 2 Samuel 12:25 — and survives mainly in evangelical-American and Western-fiction contexts (think characters in Westerns, frontier dramas, or biblical novels). The character
杰 'hero/outstanding' is the standard 'Je-/Jay-' starter, and
亚 closes many '-iah/-ia' biblical names.
